As shown,-the, screw is' fitted .in and extendsthrough a threaded opening 20 in the frame and is adapted t'obe held in Q wrench or other tool whereby the screw may a adjusted position b a check nut 21-.

It will be evident that through the medium 'of the screw 17 ,which regulates the position of the periphery of the wheel 11 roughness'of contact between'the glass andthe frame 1; and wheel b ffing 01' polishing f of the bracket or frame 1,

and is slidably mounted at its upper end n x 27 and 28, the levers nected with the hanger thereof, thus allowing a new be readily 1 and lowered to raise parts of the apparatus will be entirely eliminated, liability of injury to orbreakage of the glass will be reduced to a minimum. It will be obvious from the foregoing description that the construction is s'iicli that 11 may be movedabout the shaft'2 without altering the vrelativepositioii parts, thus allowing the device .to be lifted from the 'jilVOI'k without disturbing the adjustment of any of its parts. Furthermore, the wheel 11 may be quickly removed from the shaft 7 upon disengaging the latter, and another wheel of like-character or of, a different kind may be quickly applied in lieu wheel to be subone or interchangeable wheels of .diflerent kinds stituted for an old a to be readily and conveniently employed.

' I The means for raisingan'd lowering the device into and out of engagement with the Workcomprises a rod 22 which is pivotally connected at its lower end with the front end as indicated at 23,-

a supporting hanger 24:. Also mounted on this hanger is a pivoted hand lever 25 connected by links 26 with pairs of toggle levers- 27 being pivotally con- 24 and the levers 28 pivotally connected with" an adjustable leeve 29 on the rod 22 wherebysaid rodmay conveniently raised and bracket or frame bufling wheel out of and v of the pulleys or other working mounted and lower the carrier I into. engagement with the surface of the work, a raising, lowering. mechamsm of a simple but powerful character-being thus provided whereby comparatively heavy bufling devices may be raised in a" ready and convenient manner.

In addition to the above: stated advans tages,'git is evident that the apparatus; is

simple and inexpensive of construction, ca

pable ofbeing operated .at a-minimum cost,

and ada and efiicient manner.

I claim z:

.1. A bufiing machine comprising'a drive shaft, a vertically swinging carrier bracket journaled'at one end to .swing upon said shaft as an axis,'a bufling wheel journaled uponthe free end of saidcarrier bracket, a

, driving connection between the buffing wheel and'the drive shaft, said connection-being a raising movable with the carrier member, and lowering element connected with the free end'of the carrier'meinbei', and an over head operating device for actuating said raising and loweringelemenu 2. A buffing machine comprising a car riermember, pivotally mounted at one end to swing in a vertical plane. a. buffing wheel tlie-free-end'of said carrier journaled upon member, means for driving said bufiing ted to perform its workiin a rapid i 5 wheel, means for adjust-ably limiting the downward movement thereof, a vertically sliding raising and lowering-rod connected with-tlie free end of the carrier membergand andan overhead actuating means for raising lowering said rod.

3'. A bufling device including apivot'ally gravity controlled supporting bracket, a-- bufiing wheel .joui'naled on said bracket, means for driving said bufling wheel, means movement ofthe bracketfland' buffing wheel and'pressure'of the latter on-tlie work, n

for regulating thedo'wnw d slidable'rod pivotally connected with the bracket, and a toggle lever mechanism connected with sai d rod "whereb a supporting bracket may be'i'aised and lowered.
